"Longfiber" - Released as BETA. I'm going to work on it some more tomorrow. At this point the progressmeter has a sliding carbon fiber door instead of LCD indicators - It will have indicators soon. I'm not sure about the squared URL/search fields as opposed to the round. If we go with the round I need to anti-alias the suckers as they are jagged.
My opinion? I really can't recommend anything as it's personal preference. Some like a bright toolbar against a dark board skin for contrast - some don't. I have so many tabs I visit and most are different so I don't bother changing themes. I just stick with the theme i'm working on until I grow tired of it.
RE-EVOLUTION theme is available at my site now. Please know that this is still a "work in progress" (beta). There are some missing elements and icons need work. I want to release now as Christmas is near and I have other things to do - so it will be a while before this is complete. Thanks.
